For a Maryland PTE operating solely in Maryland, and that made a Federally deductible estimated PTE tax payment in 2020, shouldn't Lines 1 and 2 of the K-1 be identical?  ProSeries is reporting Line 2 as the Federal Income plus the tax deducted on the Federal return.  On the 502, we are taking the Federal K-1 and adding back only the actual PTE tax calculated using the 502LU.
